Video showcasing some basic implementations
The real challenge was to mimic the visuals of two small LEDs behind an orange frosted glass that reflect light onto small rotating mirrors giving the fire effect. To achieve that I used parallax.
I created a radial gradient using parallax that will mimic the light scattering trough the frosted glass.
Then I created 2D textures of an approximate blurred LED light, that is also using parallax.
Then I created small textures that will mimic the reflected light on the frosted glass with a texture panner that make them go up.
Then to finish, I duplicated the small textures that mimic fire and blurred them in some directions, after that i'm blending them with the previous one as they get higher on the surface, that mimics the reflected light going further away from the source and thus getting distorded.
All of that on an Unreal Shader (Material) used on a simple plane ! And it even looks greater in VR since it really gives a sense of depth when seen in 3D without using any geometry.
